1. B is correct period. Turgid guard cells open the stomata, while flaccid ones close them. You can't have Band D at the same time. Water does not come in through the stomata and if there is no water in the soil they will remain closed.
2. C is correct. Apical meristem.

Both B and D are correct in the first question. Plants tend to lose water through the stomata, so they would close, but it is the guard cells that control the opening and closing.
Plants produce new cells in meristems (C).

1. I would go with B because the stomata have to close to prevent water from leaving the plant.
2. and I would also go with C) meristems

1. A the stomata open - because it wants to let more water in
2. C meristems
